Some aspects of atom-field interactions in curved spacetime are reviewed. Of great interest are quantum radiative and entanglement processes arising out of Rindler and black hole spacetimes, which involve the role of Hawking–Unruh and dynamical Casimir effects. Most of the discussion surrounds the radiative part of interactions. For this, we specifically reassess the conventional understandings of atomic radiative transitions and energy level shifts in curved spacetime. We also briefly outline the status quo of entanglement dynamics study in curved spacetime, and highlight literature related to some novel insights, like entanglement harvesting. On one hand, the study of the role played by spacetime curvature in quantum radiative and informational phenomena has implications for fundamental physics, notably the gravity-quantum interface. In particular, one examines the viability of the Equivalence Principle, which is at the heart of Einstein’s general theory of relativity. On the other hand, it can be instructive for manipulating quantum information and light propagation in arbitrary geometries. Some issues related to nonthermal effects of acceleration are also discussed.

回顾了弯曲时空中原子场相互作用的某些方面。人们非常感兴趣的是林德勒和黑洞时空产生的量子辐射和纠缠过程，其中涉及霍金-安鲁的作用和动态卡西米尔效应。大多数讨论都围绕着相互作用的辐射部分。为此，我们专门重新评估了对弯曲时空中原子辐射跃迁和能级变化的传统理解。我们还简要概述了弯曲时空中纠缠动力学研究的现状，并重点介绍了与一些新颖见解相关的文献，例如纠缠收获。一方面，研究时空曲率在量子辐射和信息现象中所起的作用对基础物理学，尤其是引力-量子界面具有重要意义。特别是，人们检验了等效原理的可行性，该原理是爱因斯坦广义相对论的核心。另一方面，它对于操纵任意几何形状的量子信息和光传播具有指导意义。还讨论了与加速非热效应相关的一些问题。
